Why do some people go bald? |

There
are two reasons why people may go bald. The live hair germ centers have
either been permanently destroyed or they have been temporarily damaged.
Permanent baldness or alopecia occurs in more than 40 per cent of men and
may affect the whole head. In women it affects the crown of the head only
and never leads to complete loss of hair. Three factors often lead to
permanent baldness—heredity, age and hormone balance. There is no cure.
Other causes of permanent baldness may be injuries or diseases which produce

inborn lack of hair development and severe injuries to the hair germ centres
by chemicals. Temporary hair loss often occurs after a high fever, thyroid
disease of tuberculosis, but it grows again in most cases after the disease
cured. Drugs, X-rays, malnutrition and some skin diseases can also cause
temporary hair loss, but usually it grows again within a year. There is also
a disease called alopecia areata, in which the hair falls out in patches all
over the head. Usually the germ centers have been injured only temporarily,
and in 99 per cent of cases the hair grown again without treatment. Baldness
may occur at almost any time of life after childhood. |
